hi everybody, so far I'm working upon a GNURadio implementation of one of the functional block of the DVB-t standard, the "Inner interleaver",
my trouble in this moment is that such functional block needs to perform a permutation on a 1512-bits length chunk: i've tried to modify the step of this loop, this way: STEP=1512; for (int i= 0, i<= noutput_items, i+=STEP) for (int w= 0, w<= 1511, w+=1) out[i+w]=.. but this doesn't seem to work properly. ( I guess because I'm trying to reference items too far away from my current position in the stream). another thing i've tried is: for (int i= 0, i<= noutput_items, i+=1) for (int w= 0, w<= 1511, w+=1) out[1512*i+w]=... but this even segfaults at runtine. which is the wise way I should do interleaving on such big chunks in GNURadio? thank you guys, and best regards -- Vincenzo Pellegrini
